Looks like your isBatteryEmpty method is incorrect. It should return true only if the barCount is equal to 0 and false otherwise.

public boolean isBatteryEmpty() {
  if (barCount == 0) {
    return true;
  }    

  return false;
}

And any time you find yourself returning true or false like that, you can just return the result of the expression in the if statement between the parens.
